Introduction 


This manual has been compiled for the 
purpose of placing in the hands of the men 
who operate and those who make repairs 
to Inspirators such information as will en¬ 
able them to fully understand the operation 
of the apparatus and aid them in making 
repairs when necessary. We have endeav¬ 
ored to enumerate all the possible causes 
of Inspirator failures and to point out the 
proper method of locating the trouble and 
its remedy. In the matter of repairing 
Inspirators the manual will be found to 
contain all the information needed by the 
repairman to enable him to appreciate all 
of the vital points involved and to proceed 
intelligently and expeditiously to restore 
the Inspirator to its original efficiency, in 
the shortest time possible and with the 
least amount of new material. 

We are constantly aiming to improve 
our apparatus by simplifying the operation, 
maintaining its efficiency as a boiler feeder 
and reducing the cost of maintenance to 
a minimum. 


THE HANCOCK INSPIRATOR 


The Hancock Locomotive Inspirator is a double tube apparatus work¬ 
ing with a positively closed final overflow valve. The Inspirator consists 
of one apparatus for lifting or priming and another for forcing, each having 
its own steam nozzle and combining tube, so arranged that the lifter de¬ 
livers the water to the forcer under pressure. This feature may be clearly 
seen by an inspection of the cut inserted herein. 



The fundamental advantage of this construction, obtained with no 
other design, exists in the automatic regulation or governing of the water 
supply. Both steam nozzles receive approximately the same steam pres¬ 
sure when the Inspirator is working, the lifter tube raising the water and 
delivering it under pressure into the intermediate chamber; the forcer 
tube receives this water and delivers it into the boiler. If the steam pres¬ 
sure rises, the lifter tube will lift and deliver more water to the forcer, but 
inasmuch as there is a correspondingly greater amount of steam passing 
through the forcer nozzle, proper care is taken of this increased supply of 
water. 

As a result, the Hancock Inspirator has an extraordinary range of steam 
pressure, working equally well at 35 or 350 pounds pressure without any 
adjustment whatever. 

In addition to this advantage, the receiving of water by the forcer side 
under pressure makes the Inspirator much less susceptible to “breaking” 
under severe conditions, such as high suction temperatures or excessive 
back pressures. 


6 




The positively closed final overflow, of course, makes it impossible for 
any water to “spill” or be lost while in operation, thus insuring the delivery 
of all the water into the boiler. As the overflow nozzle is coupled to the 
overflow pipe, escapement of steam in the cab is avoided. 

In principle, the lifting and non-lifting Inspirators are precisely the 
same, the latter, however, is so designed that it works to best advantage 
when taking water under a head. 


7 


OPERATION OF THE HANCOCK INSPIRATOR 


Lifting Type 



To start the Inspirator, pull back the lever No. 137 into the first or 
lifting position, i. e., until the resistance of the forcer steam valve is felt. 
This will draw the steam valve 126-H from the main seat and admit steam 
through the steam valve No. 126-H to the lifter nozzle No. 101, at the same 
time holding the movable end of steam valve No. 126-H tighter to its 
seat. The discharge of steam from this nozzle into the lifter combining 
tube No. 102 entrains the air in the suction pipe, producing sufficient 
vacuum to lift the water. The flow of water passes through both the 
intermediate overflow valve No. 121 and the forcer combining tube No. 
104 and out of the final overflow valve No. 117. A further movement of 
the lever draws the movable end of steam valve No. 126-H from its seat 
and admits steam to the forcer nozzle No. 103 and forcer tube No. 104, 
while at the same time the final overflow valve No. 117 is .approaching its 
seat, creating sufficient pressure in the delivery chamber to close the in¬ 
termediate overflow valve No. 121. The final overflow valve No. 117, 
will be closed and the Inspirator in full operation when the lever is drawn 
back to the stop. 

Previous to January 1, 1921 the forcer steam valves for Hancock In¬ 
spirators were furnished with a lifter steam valve No. 130 or 130A. With 
this type of steam valve the drawing of the lever No. 137 to the lifting posi¬ 
tion moved the lifter valve No. 130 or 130A from its seat, admitting steam 
to the lifter steam nozzle No. 101, and pulling the lever back to the stop, 
drew the piston end of the old style forcer steam valve No. 126 or 126A from 
its seat. 


8 




The intermediate overflow valve operates automatically and its function 
is to afford relief to the lifting portion of the apparatus when priming. 

REGULATION 

The regulation of the capacity of the Hancock Inspirator is accom¬ 
plished by means of the regulating valve No. 105, which controls the 
amount of steam admitted to the lifting nozzle of the apparatus. 

When the pin in the wheel of the regulating valve is at the top, the 
Inspirator will deliver its maximum quantity of water; to reduce the feed, 
turn the regulating wheel to the right. 

HEATING 

To use as a heater, lift heater rod No. 106 until disengaged from the 
stud in the lever No. 137 and draw it back until the final overflow valve No. 
117 is closed. Draw lever No. 137 to the lifting position and regulate the 
amount of steam going back by means of the regulating valve No. 105. 

If desired, the operating lever No. 137 may be pulled back to its limit 
of travel, thus closing the final overflow valve; and the amount of steam 
necessary for heating be adjusted at the throttle on the fountain. 


9 


POSSIBLE CAUSES OF INSPIRATOR FAILURES 


Lifting Type 

Be sure that the Inspirator is receiving a sufficient supply of water , that 
is that the suction pipe is of the size recommended in this manual, that the tank 
valve is of sufficient area and that there are no leaks in the suction or syphon 
pipes. Before looking for trouble in the Inspirator itself , be sure there is no 
accumulation of lime in the branch pipe, boiler check or check shank to the 
boiler or in the overflow pipe and in case the overflow is piped into the ash pan 
that the end is not embedded in the ashes. 

When the Inspirator refuses to lift or prime, after putting the lever in 
the lifting position, with the steam connections fully open and sufficient 
pressure in the boiler to operate the Inspirator, the trouble may be due to 
one or more of the following causes: 

A leaky suction, an obstructed tank valve, hose, hose Strainer, suction 
or overflow pipe, a poor joint between piston end of forcer steam valve 
and steam entrance port, a displaced lifter steam nozzle No. 101 or lifter 
tube No. 102 or a stuck intermediate overflow valve No. 121 that will not 
lift. 


To Test for Leaks in the Suction 

Close the overflow valve No. 117 and blow steam back into the tank; 
meanwhile swaying the hose and pipe and examining all connections be¬ 
tween the tank and the Inspirator. A leak will be indicated by an issue of 
steam and should be stopped immediately upon its discovery. 

Where a syphon device is used in a tank, care should be taken to see 
that no air leaks exist, due to loose pipe threads or corrosion. When loose 
feed pipes are found they should be fastened with substantial brackets 
that will prevent their swaying or vibrating. 


To Test for an Obstruction in the Overflow Pipe 

Disconnect the pipe from the Inspirator and examine the overflow 
nozzle No. 108, making sure that it is clear. While the overflow pipe is dis¬ 
connected, try the Inspirator for lifting or priming and if the Inspirator 
works with the overflow pipe disconnected but refuses to work when it 
is connected the pipe is obstructed and must be cleared. 


10 


To Test for a Leak between Piston End of the Forcer Steam 
Valve and the Body Seat 

Close the regulating valve No. 105 and pull the lever No. 137 into the 
priming position. If the piston end of the Forcer Steam Valve seats 
properly, no steam will be seen issuing from the overflow pipe. 


To Determine Whether or Not the Lifter Steam Nozzle No. 101 or 
the Lifter Tube No. 102 has Become Displaced 

Disconnect the suction pipe from the Inspirator, insert the hand into 
the suction opening and feel if the nozzle and tube are in position. 


To Examine Intermediate Overflow No. 121 

If, after making these tests, no cause for trouble has been found, ex¬ 
amine the intermediate overflow valve No. 121 and make sure that it is 
free to lift. If it be so, the Inspirator should readily lift or prime. 


To Test for an Obstruction in the Tank Valve, Hose or Strainer 

With the tank about one-third full, start a leak by unscrewing the hose 
coupling nut, or, when a strainer is in the line, by loosening the cover until 
a stre'am about the size of a lead pencil flows therefrom. If the leak does 
not diminish upon starting the Inspirator it may safely be assumed that the 
waterway is clear to that point. On the other hand, if the leak ceases when 
the Inspirator is started it will be a positive indication that the waterway is 
obstructed and a thorough examination of the tank valve should be made 
to see that it is free from debris, such as coal, dead leaves, waste or mud and 
that it has an opening of sufficient area. In some forms of tank valves, 
while the original opening may have been ample, after continual use for 
some length of time the joints in the lifting mechanism may become worn 
to such an extent that the opening of the tank valve may be reduced so as 
to partially cut off the water supply from the hose. If such is the case it 
should be restored to its original condition. An examination of the hose 
should be made to make sure that the lining has not become loose. See 
that the combined area of the openings in the perforated plate of the strain¬ 
er is at least double the area of the suction pipe, also that any gaskets used 
in the suction line are of full sized opening. The above should also be the 
procedure if the capacity of the apparatus is impaired. 


11 


If Inspirator Lifts But Will Not Force 

When the Inspirator refuses to force water into the boiler after lifting it, 
the trouble may be due to one or more of the following causes: 

An insufficient supply of steam, excessive resistance in the delivery pipe, 
worn out tubes, an improper relation between the opening of the forcer 
steam valve No. 126A or H and the closing of the final overflow valve No. 
117, the intermediate overflow valve No. 121 being stuck open or a leak 
between this valve and its seat or between the removable seat and the body. 

To Determine Whether or Not the Supply of Steam is Inadequate 

Attach a steam gauge to the Inspirator at the oil plug. When the Inspira¬ 
tor is at work the reduction in steam pressure should not exceed five pounds 
and if a greater drop is observed the connections in the steam line should 
be sufficiently enlarged. 

To Determine Whether or Not the Resistance in the Delivery Pipe 

is Excessive 

Attach a pressure gauge to the delivery pipe near the Inspirator and 
observe the pressure indicated when the Inspirator breaks. When in a 
normal working condition, the Inspirator is capable of forcing water against 
a pressure about fifty per cent, above that of the steam supplied to it, 
although in practice the delivery should not exceed the steam pressure by 
more than ten per cent. If it is found upon trying to put the Inspirator to 
work that the delivery pressure exceeds that of the steam pressure, twenty 
or thirty per cent., the area of the openings through the delivery pipe and 
check valves should be increased until the excessive resistance is removed; 
be sure the delivery pipe is of the size recommended in this manual for the 
Inspirator being used, that the line check and boiler check valves have 
sufficient area and lift and that there is no lime formation in the delivery 
pipe or in the check shank to the boiler. If, however, the pressure in the 
delivery pipe is less than the steam pressure, it may be assumed that either 
the steam supply is restricted or the forcer tube No. 104 is worn out and 
should be replaced. 

Improper Relation Between Final Overflow Valve No. 117 and 
Compound Forcer Steam Valve No. 126A or H 

It is necessary for the successful operation of the Inspirator that the 
proper relation be maintained between the opening of the forcer steam 
valve No. 126A or H and the closing of the final overflow valve No. 117, so 
that sufficient steam to force the water into the boiler will be admitted to 


12 


the forcer steam nozzle No. 103 before the overflow valve No. 117 is closed. 
(To determine the above relation, see page 17.) 

Too much lost motion in the connections between the lever No. 137 
and the final overflow valve should not be permitted to accumulate, for 
it will disturb the relation between the forcer steam valve and the overflow 
valve which has been previously referred to. Temporary relief may be 
secured by screwing down the final overflow packing nut No. 118 to pro¬ 
duce more friction on the stem of the overflow valve and prevent it from 
being suddenly slammed to its seat when near the point of closing. The 
proper course to pursue would be to have the Inspirator removed and re¬ 
paired so that the lost motion would no longer exist. 

Intermediate Overflow Valve No. 121 Stuck Open or Leaking 

If the foregoing tests do not result in the disclosure of the trouble and 
it is found that the Inspirator still refuses to force water into the boiler, an 
examination of the intermediate overflow valve No. 121 should be made 
to see that it does not stick open or that there is no leak between this 
valve and its seat or between the removable seat and the body. If the 
Inspirator goes to work, but gradually becomes weaker and finally breaks, 
it may safely be assumed that the intermediate overflow valve leaks. 

If there is a leak of steam at the overflow when the Inspirator is shut off it 
may be due to one or more of the following causes. A leaky lifter steam 
valve No. 130 if old design forcer steam valve is used, or a leaky forcer 
steam valve 126A or H, or a leak between the removable seat ring and the 
body. 

If there is a leak of steam and water at the overflow the main steam valve 
on the fountain should be closed. If the leak continues it will indicate a 
leaky boiler check valve. 

If water leaks from the overflow when the Inspirator is at work the final 
overflow valve No. 117 should be reground and, if necessary, the removable 
seat made tight on its seat in the body. 

After any or all of the possible causes of trouble have been investigated 
and remedied the Inspirator should take water from the tank and continue 
to work until air begins to enter the suction when, of course, the Inspirator 
will break. 


13 


INSTRUCTIONS FOR REPAIRING THE LIFTING 
INSPIRATOR 


Remove from the body all of the external and internal parts and by 
a careful examination of them determine which, if any, are so much worn 
as to require replacement with new parts. Bear in mind the fact that the 
elimination of all lost motion in the connections between the lever No. 137 
and the final overflow valve No. 117 is fully as essential to the successful 
operation of the Inspirator as a perfect condition of the tubes and nozzles. 

Applying a New Forcer Steam Valve 

If it is found necessary to apply a new forcer steam valve a so-called 
repair valve should be used. This valve as furnished has an extra amount 
of stock on the seat to compensate for the material removed from the body 
seat by reseating. To properly machine this valve, it should be screwed 
onto a steel mandril fitted to the spindle of a lathe. The back end of the 
valve is faced so that if it is brought up against the face of the mandril it 
should be true. Be sure there is no lost motion in the threading of the 
mandril as, if the forcer steam valve does not fit tight, it will not run true. 
The cut illustrates the usual form of mandril with the valve screwed onto it. 



ThreadTo Fit 
Engine Lathe Spindle 


To properly fit the compound forcer steam valve to the Inspirator body 
we have designed and are prepared to supply gauges as illustrated. In¬ 
structions for their use follow. 

Insert gauge until figure 4 rests firmly on seat, then push in handle 1 
until gauge 3 engages with its seat, tighten up screw 2 to hold adjustment, 
set ring of gauge 5 on part 4 with the faces engaging, then set pointer 6 to 


14 


















































the proper seat on gauge 3 (see next paragraph), then with this setting 
remove gauge 5 and place it on the piston end of the forcer steam valve, 




5 


taking care to hold this valve to the extreme end of its travel, then scratch 
with pointer 6 on seat of main valve cutting seat back to this mark and 
grind valve to its seat in Inspirator Body. 

If the valve to be repaired is of the type equipped with a lifter steam 
valve (126A), the gauge should be set to a point ^ of an inch back of the 
upper shoulder on the 45 degree or flat seat as Injector being repaired 
requires; this will allow clearance in the piston end while seating. 

If the valve is of the type without the lifter steam valve (No. 126H) the 
pointer should be set ^ of an inch back of the upper shoulder of the 45 
degree or flat seat. 

In applying the compound forcer steam valve to the Inspirator body 
the following points will be observed. 

Valve Seats 

All Hancock Lifting Inspirators, as now made, have solid valve seats 
excepting the Final Overflow Valves which have removable seats; however, 



15 





































forcer steam seat rings can be inserted when the solid body seats have been 
worn through, thus prolonging the life of the bodies. If a removable seat 
is applied be sure that it makes a perfect joint between itself and the body. 
We make special tools for easily applying or removing these seats when it 
becomes necessary to make renewals. (See pages 20-21.) 

Whenever it becomes necessary to reseat any of the valve seats the re¬ 
seating tools, shown on pages 22-23 should be used before regrinding. 

To secure the best results the reseating tools should be used in the 
following manner: 

Screw the cast iron guide piece (B) to its shoulder. The cutter (G) is 
then fed against the seat by nut (A), care being taken to remove as little 
metal as possible to get a true seat, consequently nut (A) should be fed 
very slowly and carefully. After this operation the valve can be easily 
reground in the usual manner. 

In grinding, emery should never be used. After reseating, sand or 
quartz should be used. 

Final Overflow Disc 

In repairing the Final Overflow Disc, if it becomes necessary to square 
up its face, the short cylindrical projection under the face should be left 
the same diameter, and the cylindrical projection as much longer as 
has been squared from the face of the disc. In squaring up and reseating 
the seat a proper tool for doing this should be used, and as little taken from 
the seat as possible to make it true. 

The distance from the point where the self adjusting disc valve seats to 
the center of the pin (Nos. 145, 225, 345, 445 and 545) in the lever, will 
remain the same, although the valve and its seat has been reseated. The 
point of opening to the Forcer Steam Nozzle will bear the same relation to 
the amount of opening of the Final Overflow Valve (Nos. 117-C, 250, 358, 
458 and 558) that was originally established, regardless of the increased 
travel of the lever; so that while the lever, when closed, will go in further 
and the valve will travel further on the self adjusting disc stud, the relation 
above referred to will not be disturbed. 

Assembly 

After having restored all of the valve seats in the body to a perfect con¬ 
dition, grind the forcer steam valve 126A or H and couple it securely to the 
steam valve stem No. 146, which has already been inserted into the steam 
valve bonnet No. 158 and packing nut No. 128. These parts will then be 
ready for application to the body. Next grind the intermediate overflow 


16 


valve No. 121 to its seat and see that it fits properly in the bonnet No. 120, 
for a loose fit at this point will not insure a proper seating of the valve and 
might cause the Inspirator to fail. The lift of the intermediate overflow 
valve must not be permitted, by reason of reseating or grinding, to exceed 
its original limit by more than y % ". The original lift for this valve in all 
sizes, Types A, B, Composite, E and F, is jV'; Type G, Excessive lift 
may be taken up by slipping a washer of proper thickness over the stem of 
the valve. The final overflow valve No. 117 should then be ground to its 
seat and care should be taken to see that the joint between the removable 
seat and the body is tight. The tubes and nozzles should then be screwed 
to their seats being careful to note that all bear the same capacity number, 
and all of the other parts of the Inspirator assembled in place. A certain 
definite amount of steam valve opening is necessary for the best per¬ 
formance of the Inspirator and this amount is determined by pushing the 
lever No. 137 toward the body as far as it will go and with some sharp in¬ 
strument mark, the stem No. 146 close to the packing nut No. 128, then 
pull the lever back until the final overflow valve No. 117 is closed and 
measure the distance from the mark on the stem to the packing nut. This 
indicates the travel of the forcer steam valve and for types A, B and Com¬ 
posite should be at least yg" for a No. 7 Inspirator, for a No. 8, 
No. 9 or No. 93^ and for a No. 10 or No. 11 Inspirator. A slightly 
greater travel will not affect the working of the Inspirator, but in all cases 
it should be no less than the prescribed distances. 

Repair men should carefully discriminate between those parts which 
are completely worn out and those which may be made to perform still 
further service. A forcer tube No. 104, which may become somewhat 
worn on the delivery end, may be reamed out and made to give a considera¬ 
bly longer service. When reaming, forcer tube reamers made by the 
Hancock Inspirator Co. only should be used, and care taken to leave at 
least }/s" of the throat, or smallest diameter of the tube. If throat is en¬ 
larged the tube is spoiled. A forcer steam valve No. 126A or H may have 
its seat trued up in a lathe and give service for an appreciable length of 
time. 

These general instructions for repairing will apply to all types of Han¬ 
cock Lifting Inspirators. Types E, EA, F and G have the stroke of the 
steam valve stem controlled by a block or capacity plate No. 364, 464 or 
564, on which is indicated the maximum capacity in gallons per hour. The 
Inspirators, types E, EA, F and G, have a wide range of capacities, by 
changing the tubes and nozzles from 2500 to 5500 gallons per hour with a 


17 


minimum capacity of about 50 per cent, of the maximum, and whenever a 
change is made in the size of the tubes and nozzles a capacity plate No. 
364, 464 or 564, must be applied corresponding to the capacity of the tubes 
in order to establish the proper movement of the steam valve. This move¬ 
ment should be at least 3^" for 2500 gallons, ts " for 3000 gallons, " for 
3500 gallons, %" for 4000 gallons, ff" for 4500 or 5000 gallons and for 
•5500 gallons. The movement for all sizes of Type G Inspirators should be 
Should it be found necessary at any time to supply a new crank- 
jholder No. 322, 422 or 522, which numbers indicate this part on the Types 
E, F and G respectively, apply a capacity plate corresponding to the 
capacity of the tubes to be used. Having applied the crank-holder, pull 
out the lever to the extreme and measure the stroke of the stem No. 346, 
446 or 546 and if this be found to be greater than the prescribed amount, 
face off that part of the crank-holder which rests upon the capacity plate 
until the correct travel is obtained.

THE HANCOCK INSPIRATOR 
Type Composite 



The Hancock Inspirator Type Composite comprises two separate In¬ 
spirators within one body, which may be operated separately or simul¬ 
taneously as desired. Made in four sizes of body taking nine different 
sets of tubes, sizes Nos. 4 to 12, inclusive. Each apparatus has an inde¬ 
pendent suction pipe, delivery pipe and line check valve, thus enabling it 
to be operated independently of the other. There is but one steam pipe, 
one main steam valve and one overflow pipe required. The operation is 
the same as for Types A and B and the internal construction is the same.

THE HANCOCK INSPIRATOR 
Types E and EA 



Above sectional view shows a Type E Inspirator, but is correct for all 
parts of the Type EA except the body. 

When ordering repair parts, use both numbers and names given on 
opposite page; also give type of the Inspirator for which they are required. 

In addition, when ordering tubes or nozzles the capacity number (see 
preceding page) must be stated. 

NOTE.—The tubes, nozzles and capacity plate (part No. 364) each 
has its capacity number either stamped or cast upon it. It is absolutely 
essential that each of these five parts (Nos. 301, 302, 303, 304 and 364), when 
applied to an Inspirator , bear the same capacity number.

GAB LEVER EXTENSIONS FOR HANCOCK INSPIRATORS 
Types A, B, E, EA, F, G, Composite, H-N-L and L-N-L 



The above shows the levers, rods and joints we furnish when it is 
necessary to place the Inspirators outside of the cab. The rods are in 
two pieces, each with one end fitted with its attachment and are designed 
to be welded up to the desired length. Although the joint connecting the 
rod to the Regulating Spindle is made with a loose fit to provide for align¬ 
ment, the rod should be set as nearly as possible in line with the spindle, 
and both rods should be made to work freely in front end of cab. In welding 
up the rod for the Regulating Spindle, care should be taken to have the pin 
in Regulating Wheel stand at top when Regulating Valve is wide open. 
The rod can be twisted to effect this.

THE HANCOCK DETACHABLE COUPLING NUT 



This coupling nut was designed for quick and easy removal, whenever 
the parts become worn or injured, without disturbing the pipe connections. 

It is especially adapted for use in connection with copper pipes where 
the collars are brazed on, for if the threads in the coupling become damaged 
or the grooves for the spanners become distorted, a new Hancock Detach¬ 
able Coupling Nut can be substituted without disturbing the brazing or 
jointed ends. 

The Hancock Detachable Coupling Nut has been subjected to very 
severe tests as to its strength, which is equal to the solid coupling nuts of 
the same size. The collar is made of steel which will not be damaged by the 
use of a hammer and set. It is made in sizes to fit all types of Hancock 
Locomotive Inspirators. 

In ordering specify by name “The Hancock Detachable Coupling Nut” to 
distinguish it from the regular couplings, also state size and type of Inspi¬ 
rator and for which connection wanted and whether for iron or copper pipe. 

These coupling nuts are threaded to fit Hancock Inspirators, Main 
Steam Valves or Boiler Check Valves.

THE HANCOCK NON-LIFTING INSPIRATOR 
Types H-N-L and L-N-L 
Description 

These types consist of a body, to be attached in an upright position, 
containing two sets of tubes the same as in lifting Inspirators, but modified 
to meet non-lifting conditions. 

These Inspirators are also provided, on the suction side, with an an¬ 
nunciating or alarm valve which works automatically, is heavy enough to 
overcome the pressure of water in the tank and is piped to the gage cock 
drip funnel or a separate funnel, as may be desired, under the eye of the 
engineer, so that if the Inspirator breaks this pipe discharges steam or 
water in full view of the engineer. This valve is also provided with an 
opening so that any water left in the pipe will drain out to prevent freezing. 
The drip opening is closed when the valve is open. 

These Inspirators are also provided with a check valve in the suction 
end to prevent blowing off the hose should the Inspirator “break” and to 
ensure the opening of the annunciator valve. This check valve is provided 
with an opening through it sufficiently large to use as a heater. 

The lifting side of the Inspirator is provided with a separate steam pipe 
connecting with the main steam pipe at the operating valve. This pipe at 
the operating valve is provided with a regulating valve for regulating the 
supply of water from maximum to minimum, the same as the regulating 
valve in lifting Inspirators. 

Operating Valve 

The Operating Valve is controlled by one lever. Attached to this valve 
are two pipes, one supplying steam to the forcer tubes, the other supplying 
steam to the lifting tubes. 

Mounted on the operating valve is a regulating valve for controlling 
the volume of steam to the lifting tubes for regulating the capacity and for 
heating tank water. This valve is operated in the same manner as the 
regulating valve on lifting Inspirators, see page 9. 

Overflow Valve 

The overflow valve is operated by means of a handle attached to a rod. 
This rod passes down through a stand on the running board in front of the 
engineer, and is equipped with proper joints to connect with the overflow 
valve. This is the only operative valve directly attached to the Inspirator; 


53 


THE HANCOCK NON-LIFTING INSPIRATOR 
Types H-N-L and L-N-L 

(Continued) 

it is always kept closed except when starting the Inspirator, and as this 
valve closes positively with a screw, there is no opportunity for water to 
escape or waste when the Inspirator is working, or when shut off. The only 
escape of water being while starting. This valve is closed by turning the 
handle to the right. 

Operation 

To start the Inspirator under normal conditions, the regulating valve 
being well open, the final overflow valve should be opened by turning the 
handle about half a turn to the left (but when the Inspirator is required 
to lift or dislodge hot water from the suction pipe the overflow valve should 
be opened to the fullest extent.) Draw back the lever of the operating 
valve into the lifting or priming position, the same as for a lifting Inspira¬ 
tor, then draw the lever back as far as it will go and close the final overflow 
valve, whereupon the Inspirator will be in full operation. By means of the 
regulating valve the capacity of the Inspirator may be reduced to about 
thirty-three per cent, of its maximum. After very little practice it will be 
found that the drawing back of the operating valve lever and the closing 
of the final overflow valve may be performed almost simultaneously. 
Should the Inspirator break or fail to work the fact will be indicated by the 
blowing of steam from the alarm pipe. 

To stop the Inspirator, shut off the operating valve, always leaving the 
overflow closed. The overflow valve should remain closed until the In¬ 
spirator is to be started again. 

To Use as a Heater 

With overflow valve closed, shut the regulating valve tightly and pull 
operating handle to priming position. Then open regulating valve until 
required amount of steam is obtained. 

Repairing 

Examine the steam nozzles and tubes, inserting new parts where nec¬ 
essary, being careful to see that all nozzles and tubes also capacity plate 
bear the same capacity number. 

If the seats for the operating valves and auxiliary disc are found scored 
or cut, reseat them with tools shown on pages 22-23, removing as little 
metal as necessary to make a good seat. 

Grind all valves to their seats and assemble. See that there is a strainer 
in both the top and bottom of the alarm valve body to prevent the entrance 
of dirt also that the alarm valve when replaced is put back right side up. 


54 


THE HANCOCK NON-LIFTING INSPIRATOR 
Types H-N-L and L-N-L 

(Continued) 

Liming Out the Non-Lifter 

To lime out the Non-Lifting Inspirator remove the cap No. 1016 
above the intermediate overflow valve and the plug No. 641 underneath 
the lifter tube, leaving the intermediate overflow valve No. 1017 on its 
seat. Pour acid solution (1 part muriatic acid, 10 parts water) in on top 
of the intermediate overflow valve untill it ceases to react and clear 
solution appears at the plug opeping underneath the lifter tube, indicating 
that the lime has been removed. Next open the final overflow valve No. 
1022 to draw off the acid and wash out the remaining acid by pouring 
water on top of the intermediate overflow valve, first closing the final 
overflow valve No. 1022. If the engine is under steam, replace the cap 
and plug and wash out the Inspirator by priming. 

Application 

The operating valve and overflow handle should be located in the cab, 
convenient for operation by the engineer. 

The Inspirator body should be fastened to the frame of the engine by 
means of a substantial bracket extending out from the frame, and located 
under the cab below the level of the bottom of the tank, if possible. The 
copper pipes connecting the operating valve in the cab with the Inspirator 
body should never be straight, but should contain an “S” bend to allow for 
expansion and contraction in both the pipes and between the boiler and the 
frame. The alarm pipe can be either of iron or copper and the alarm nozzle 
should be located sufficiently above the gauge cock drip funnel or a special 
drip pipe provided for the purpose, to enable the engineer to see the dis¬ 
charge. 

The Hose Strainer should be securely fastened by a substantial bracket 
and coupled to the Inspirator so as to avoid all quarter turns or bends in 
the suction pipe. 


55 


THE HANCOCK INSPIRATOR 
Type H-N-L

THE HANCOCK NON-LIFTING INSPIRATOR 
Type M-N-L 
Application 

This Inspirator should be located under the Cab at a level below bottom 
of tank and attached to a sufficiently rigid bracket to prevent vibration. 
Two valves, the Suction Valve and Overflow Valve require extension rods 
and their Running Board Stand (No. 2395), should be located conveniently 
for operating, usually in front and close to the Engineer’s or Fireman’s 
seat. 

Operating Lever 

The Operating Lever should be attached to either the back head, the 
side of the boiler, or, in extreme cases, on the side of the steel cab by means 
of a heavy bracket. This lever should be so placed as to be within easy 
reach of the engineer’s hand and yet should be so located as to give easy 
access to other cab fittings. A iron pipe connects this lever with the 
Inspirator, by means of which the latter is operated. An adjustment is 
provided to take care of the wear of parts, due to regrinding, etc., and to 
maintain the travel of the lever. 

Connections 

The connecting pipes and fittings should all have sectional areas at 
least equal to those listed on page 67 under the heading, Pipe Connections. 

Pipe Connections and Size of Fittings 

Steam. Steam should be taken from a point where it will be obtained 
dry and at full pressure under all conditions. We strongly recommend that 
the main steam valve to the Inspirator be screwed or flanged directly to the 
boiler shell or backhead and connected inside by a full sized independent 
dry pipe to the steam dome and located at some distance from the main 
dry pipe. The main steam valve to the Inspirator should be of the angle 
rather than globe type wherever possible as an angle valve offers less resist¬ 
ance to the flow of steam. 

All non-lifting Inspirators are furnished with flanged connections and 
may be used with nipples brazed to copper pipes or the copper pipe may be 
flanged over the nipple. 

The pipe leading from the main steam valve to the Inspirator should in 
all cases be of copper and at least of the size designated. 

Suction. The tank valve should have sectional areas considerably in 
excess of the full hose area specified even after reasonable wear of the pins 
and rods in its connections. The total area through the holes of the strainer 
(either in the tank well or hose line) should be at least double the pipe area 
specified for the suction connections. 

The suction connection of all type M-N-L non-lifting Inspirators is 
furnished with threaded nipple for iron pipe. Any desired length of pipe 
may be used to connect with strainer which is also tapped to size corres¬ 
ponding with the nipple on the Inspirator. 


64 


THE HANCOCK NON-LIFTING INSPIRATOR 
Type M-N-L 


Operation 

A sectional line cut showing the internal construction oi’ this Inspirator 
will be found on page 68. 

Starting and Shutting off. To start the Inspirator, open the over¬ 
flow valve, make sure suction valve is open, pull lever back two to three 
notches or until the water is coming freely from the overflow, then pull the 
lever back to full stroke and close overflow. To stop Inspirator, push lever 
forward to full end of stroke and drop the latch. Be sure lever is pushed 
forward to full end of stroke before dropping the latch, otherwise the forcer 
valve will not be seated, causing the seats to rapidly develop leaks. 

Opening the suction and overflow valves (Nos. 2238 and 2249) by means 
of handles, allows the water to flow freely through the tubes which is nec¬ 
essary before steam is applied. A slight movement of the lever admits a 
small quantity of steam to the lifter steam nozzle (No. 2201) and starts 
circulation of the water. A further movement of the lever, drawing it back 
as far as it will go, fully opens the forcer steam valve, admitting the full 
quantity of steam to both steam nozzles. 

Regulation 

For full capacity of the Inspirator, open the suction valve by means 
of the regulating wheel in cab to its full opening. Any desired quantity 
of water within the range of the Inspirator can be obtained by adjusting 
this valve. To reduce the capacity, turn valve handle to the right. 

To Use as a Heater 

To use the Inspirator as a heater see that overflow is closed and suction 
valve open, then pull operating lever back two or three notches. This will 
allow sufficient steam to pass through the hose to heat the water. Care 
should be taken not to pull lever open enough to lift alarm valve and allow 
steam to escape through pipe into cab. 

Maintenance and Repairs 

All valve seats in these Inspirators should be refaced by using proper 
tools made for the purpose, see pages 22-23 and then reground in the 
same manner as is practiced with ordinary globe and angle valves. 

Tubes and Nozzles 

These may be removed or inserted with wrenches as shown on pages 
20 - 21 . 

In changing the tubes and nozzles from one capacity to another, all four 
must be changed. Each has its capacity either stamped or cast upon it and 
it is absolutely essential that each of these four parts, (Nos. 2201, 2202, 
2203 and 2204) also the capacity plate, (No. 2336) as applied to an 
Inspirator, bears the same capacity number. Instructions for applying 
and repairing Forcer Steam Valves will be found on pages 14 and 15. 

65 


THE HANCOCK INSPIRATOR 
Type M-N-L 



The Hancock Non-Lifting Inspirator Type M-N-L is made in two differ¬ 
ent body sizes. 

No. 11 is adapted to six capacities of from 3000 to 5500 gallons per hour, 
by the insertion of different interchangeable sets of tubes and nozzles. 

No. 13 is adapted to six capacities of from 5000 to 7500 gallons per 
hour by the insertion of different interchangeable sets of tubes and nozzles. 

All repairs to this Inspirator can be made without the necessity of dis¬ 
connecting any pipe joints.

THE HANCOCK BOILER TESTER, FILLER AND WASHER 

This is a double tube apparatus combining an ejector which does the 
filling and washing, with an injector which is capable of producing the pres¬ 
sure necessary for testing a boiler. Instructions for operating are cast on 
the body and if followed, a novice can successfully and efficiently operate 
it without difficulty. 

Installation 

The Hancock Boiler Tester, Filler and Washer should be installed as 
near the steam supply as possible in order to get a continuous, steady flow 
of pressure and eliminate condensation. 

If the main steam line from the boiler to this apparatus is no larger than 
2" inside diameter there must be no open lines between the boiler and tester. 

Make pipe connections full size as per specifications on page 70. Pres¬ 
sure gauges connected to the steam line just above the tester and the water 
line, to part 1163, will aid greatly in securing the correct water pressure as 
per table on page 71 which is very essential when operating the apparatus 
as a tester. 

Filling and Washing 

For. this service this apparatus has an extremely large capacity of water 
per hour, the capacity depending on the water and steam pressure available, 
and will deliver warm or hot water (see table below) as desired. If the de¬ 
livery is interrupted by closing the valve at the discharge nozzle for the 
purpose of changing the nozzle from one opening to another, it will resume 
operation when the valve is opened without any other adjustment. Care 
should be taken not to stop the flow of water too long otherwise steam will 
flow back into the water pipe and overheat the water. 

The following table No. 1 gives information in regard to capacity, de¬ 
livery temperatures and pressures, suction water temperatures and pres¬ 
sures for various operating steam pressures when using the apparatus as a 
washer.

Note. The Suction Temperatures are winter temperatures. As the 
temperature will increase during the summer, this will of necessity increase 
the delivery temperatures. For every degree added to the suction tempera¬ 
ture, the delivery temperature will be increased one degree. 

With Steam Pressure at the Boiler Tester shown in Col. 1 and with a 
Suction Temperature of water shown in Col. 2, a Delivery Temperature is

obtained as shown in Col. 3. Col. 4 shows the Suction Pressure that should 
be maintained at the suction end for washing purposes. Its equivalent in 
suction head in feet is shown in Col. 5. The result will be the delivery or 
nozzle pressure as shown in Col. 6 and the gallons per hour delivered shown 
in Col. 7. The information given in this table covers the use of either wash¬ 
out nozzle. 

Particularly aim to obtain as nearly as possible the Suction pressures as 
shown in Col. 4. This can be done by the regulating valve in the suction 
and a gauge should be used to accomplish this purpose. 

Table No. 2 with similar columns is given to show the suction pressures 
and the resultant capacities for filling purposes:

Note. The Suction Temperatures are wintet temperatures. As the 
temperature will increase during the summer this will of necessity increase 
the delivery temperatures. For every degree added to the suction tempera¬ 
ture, the delivery temperature will be increased one degree. 

Care should be taken to set regulating valve No. 1108 just tight enough 
to stop leakage, so that any excess pressure building up in delivery line, 
while valve at discharge nozzle is closed, will open the regulating valve and 
permit a discharge at this point. Otherwise, the excess pressure is liable to 
damage hose. 

Testing 

For this service the apparatus has a capacity of over 3000 gals, per hour, 
will deliver water at temperatures up to 280° Fahr., and will apply test 
pressures of 600 lbs. or more, per square inch, the maximum efficiency of 
apparatus depending on the steam and water pressures available. See table 
below. 

To Operate as a Tester 

Regulate valves as per instructions cast upon the body, care being 
taken to open wide the regulating valve. Regulate water pressure in water 
line with throttling valve to suit available steam pressure (see table below) 
and pull lever No. 1137, gradually into full open position—close regulating 
valve gradually with handle No. 1110 until desired pressure on test gauge 
No. 1177 is obtained. 

To maintain the desired pressure in water line it will be found necessary 
to slightly open throttling valve in water line as the handle No. 1137 is 
pulled into full open position.

Regulation of Water Supply 

As the water supply to The Hancock Boiler Tester, Filler and Washer 
must always be under pressure, it is necessary to provide some means for 
controlling the water supply. For this purpose we recommend The Han¬ 
cock Globe Valve. 

Care should be taken that the steam pressure used should have the pro¬ 
per water pressure supplied, as shown in the above table. 

General 

The Hancock Boiler Tester, Filler and Washer is well adapted for use in 
Round Houses and Repair Shops. If used in a Round House, it may be 
permanently located near the wash-out pipes and take its water either from 
an overhead tank or the City mains. 

If, when used in a Repair Shop, it is more convenient to have it portable, 
it can be used that way and will be found equally as efficient as if per¬ 
manently located. 

The choking device interposed between the delivery chamber of the 
apparatus and the pressure gauge, prevents the momentary and violent 
fluctuations of pressure from injuring the gauge. 

Do not locate this apparatus so far from the source of steam supply that 
there will be an appreciable reduction in pressure or the steam become 
badly saturated.
